    Abstract: Molecular dynamics simulation is used to study nanoindentation of the self-assembled monolayers
    (SAMs) on an Au surface. The interaction of SAM atoms is described by a general universal force field
    (UFF), the tight-binding second-moment approximation (TB-SMA) is used for Au substrate, and the
    Lennard-Jones potential function is employed to describe interaction among the indenter, the SAMs, and
    the Au substrate atoms. The model consists of a planar Au substrate with n-hexadecanethiol SAM
    chemisorbed to the substrate. The simulation results show that the contact pressure increases as the
    SAMs temperature increases. In addition, the contact pressure also increases as the depth and velocity of
    indentation increase.
